Hi all,

I am running the ESP Iperf example to test the wifi throughput. Refferd to the documentation I should expect a (air on lab) throuput of 20 Mbit/s and a throughput of 50-70 Mbit/s in a shieldbox.

-> docu: https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-guides/wifi.html#esp32 ...

Yes. Note you can send packets larger than 1500 bytes, they'll simply get sent in chunks of 1500 bytes and reassembled automatically on the other side.

so no data will be lost right?

But I think getting the data in chunks and reassembled the data will slow dow the speed connection is that right?

Is there an upper limit on how many characters you can send at a time with client.print()?

I am sending a 1000 Byte string over tcp/ip (wifi)?

and if there is a limit where can I find it in the datasheet?

Thank you all

Hello all,

I have a mqtt applecation using esp32 board.

I have 2 questions:

1) In which document can I find information about the MTU WIFI size of an ESP32? I have googled that and in the other forums they say 1500 Byte but I cant find the Information in the datasheet or in a specific document ...

Hello all,

I already have a I²C communication between an ADXL345 sensor and a ESP32 board using I²C. But unfortunatlly i was not able to get it work using SPI interface. Can please anyone help me if there is any example?


Thank you all
